Introduction

Logarithmic equations are a fundamental concept in mathematics, and solving them requires a deep understanding of the properties of logarithms. In this article, we will explore the concept of logarithmic equations and provide a step-by-step guide on how to solve them. We will also examine a specific problem, which is equivalent to $\log _{\frac{1}{2}} 462$, and provide solutions to three different options.

What are Logarithmic Equations?

A logarithmic equation is an equation that involves a logarithm, which is the inverse operation of exponentiation. In other words, a logarithmic equation is an equation that involves a variable in the exponent of a number. For example, the equation $\log _a x = y$ is equivalent to the equation $a^y = x$.

Properties of Logarithms

There are several properties of logarithms that are essential to solving logarithmic equations. These properties include:

  • Product Rule: $\log _a (xy) = \log _a x + \log _a y$
  • Quotient Rule: $\log _a \left(\frac{x}{y}\right) = \log _a x - \log _a y$
  • Power Rule: $\log _a (x^y) = y \log _a x$
  • Change of Base Formula: $\log _a x = \frac{\log _b x}{\log _b a}$

Solving Logarithmic Equations

To solve a logarithmic equation, we need to isolate the variable. This can be done by using the properties of logarithms. Here are the steps to solve a logarithmic equation:

  1. Isolate the logarithm: Move all terms except the logarithm to the other side of the equation.
  2. Use the properties of logarithms: Use the product rule, quotient rule, power rule, or change of base formula to simplify the equation.
  3. Solve for the variable: Once the equation is simplified, solve for the variable.

Which is Equivalent to $\log _{\frac{1}{2}} 462$?

Now, let's examine the specific problem, which is equivalent to $\log _{\frac{1}{2}} 462$. We will provide solutions to three different options.

Option A: $\frac{\log _{\frac{1}{2}} 462}{\log _{422} \frac{1}{2}}$

To solve this option, we need to use the change of base formula. The change of base formula states that $\log _a x = \frac{\log _b x}{\log _b a}$. In this case, we can rewrite the equation as:

log12462log42212=log12462log12422\frac{\log _{\frac{1}{2}} 462}{\log _{422} \frac{1}{2}} = \frac{\log _{\frac{1}{2}} 462}{\log _{\frac{1}{2}} 422}

Using the change of base formula, we can simplify the equation as:

log12462log12422=log422462\frac{\log _{\frac{1}{2}} 462}{\log _{\frac{1}{2}} 422} = \log _{422} 462

This is not the correct solution, as we need to find the equivalent of $\log _{\frac{1}{2}} 462$.

Option B: $\frac{\log 462}{\log \frac{1}{2}}$

To solve this option, we need to use the change of base formula. The change of base formula states that $\log _a x = \frac{\log _b x}{\log _b a}$. In this case, we can rewrite the equation as:

log462log12=log12462\frac{\log 462}{\log \frac{1}{2}} = \log _{\frac{1}{2}} 462

This is the correct solution, as we have found the equivalent of $\log _{\frac{1}{2}} 462$.

Option C: $\frac{\log \frac{1}{2}}{\log 462}$

To solve this option, we need to use the change of base formula. The change of base formula states that $\log _a x = \frac{\log _b x}{\log _b a}$. In this case, we can rewrite the equation as:

log12log462=log46212\frac{\log \frac{1}{2}}{\log 462} = \log _{462} \frac{1}{2}

This is not the correct solution, as we need to find the equivalent of $\log _{\frac{1}{2}} 462$.

Conclusion

In conclusion, solving logarithmic equations requires a deep understanding of the properties of logarithms. By using the product rule, quotient rule, power rule, and change of base formula, we can simplify logarithmic equations and solve for the variable. In this article, we examined a specific problem, which is equivalent to $\log _{\frac{1}{2}} 462$, and provided solutions to three different options. We found that option B, $\frac{\log 462}{\log \frac{1}{2}}$, is the correct solution.
